provements 1n Player-Grand Pedals; and

' we do hereby declare the following to be a full, clear, and exact 7 description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to player piano pedals, and especially topedals adapted to actuate player grands; and has for an objectv to provide improved means whereby the pumper pedals are bodily removed from engagement withthe lyre.

A further object of the" invention is to provide a base carrying'pedals pivotally secured thereon, with a closure for such base to inclose the pedals, and means for con-' necting the base to a piano lyre.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a view of the improved pedal structure in side elevation. Fig. 2 is a view of the improved pedal structure in front elevation. Fig. 3 is a perspective view of the pedal base and closure removed from the piano. Fig. 4 is a sectional view through the base and pedals taken on line 44 of Fig. 3. Fig. 5 is a detail fragmentary view showing the means of connecting the links of the pedals with the bell-crank lever.

Like characters of reference designate corresponding parts throughout the several views.

The improved pedal structure which forms the subject matter of this application is associated with a lyre 10 of a player piano of substantially the usual and ordinaryform. At the foot of the lyre plates 11 are secured to the ends of the base block forming a chamber between such plates and the base block to receive the lower ends 12 of the bell-crank levers. The bell-crank levers are pivoted at 13 to the head block 14 which in turn is secured directly tothe bed of the piano. The rear ends 15 ofthe bell-crank levers are adapted to engage directly with the bellows or feeders'of the player mechanism or through any convenient intermediate or intervening mechanism. It is obvious that when the bell-crank levers are swung upon their pivots the ends 15 connected with the bellows will cause such bellows to alternately contract and expand in the usual well known manner. To operate the bell-crank levers manually a base 16 is provided which is proportioned to slide under the base block 17 of the lyre as shown particularly at Fig. l and is secured in such association by any approved fastening means. As shown in the drawings bolts 18 are slidably mounted in holes throughthe base 17 and have heads or other engaging members 19 by which such bolts may be lifted manually and inserted in the sockets 20 of the base-board 16. It will be apparent, therefore, that when the base-board 16 is slidably inserted under the base block 17 and the pins 18 inserted in the sockets 20 such base-board 16 will be rigidly secured removably to such base block 17-. Upon the base-board 16 pedals 21 are mounted in substantially the usual and ordinary manner and provided with links 22 pivotally secured one to each of said pedals. The ends of the links 22 opposite their pivoting to the pedals are provided with constricted notches 23 proportioned to engage over pins 24 carried by the arms 12 of the bell crank levers. It will be apparent, therefore, that as the pedals 21 are operated manually in the usual manner the bell-crank levers will be swung upon their pivots to operate the bellows of the player mechanism.

For storage purposes and convenience in handling a closure 25 is provided proportioned to cover the base-board 16 and with a cut-out portion 26 proportioned to embrace the base block 17 and side plates 11 so that the closure 25 may be placed in position over the pedals while the base-board 16 is still in engagement with the lyre. To enable the closure to be put in position the links 22 are lifted ofl from the pins 24 and the links swung in under the pedals, whereupon the latter will drop to rest upon the cleat 27 as shown particularly at Fig. 4. Fastening means 28 are provided for securing the closure upon the base-board 16 and a handle member 29is also'provided for convenience in removing the pedal mechanism from the lyre and handling. It will be apparent that with the device associated as shown at Fig. 3 the base-board may be slidably inserted under the base block of the lyre and the pins 18 inserted into place before the closure is released and removed from the pedals. In removing the pedal structure the pedals are first folded down to the position shown at Fig. 4, the closure then put in place and secured by its securing means 28, the pins withdrawn and the entire pedal structure bodily removed.

\Ve claim: 7

1. The combination with a piano lyre having a base block provided with upright holes, and levers carried by the lyre and adapted to operate the pneumatic mechanism; of a pedal support including a base adapted to be passed'under said block and havin sockets toregister with the holes therein, bolts removably mounted in said holes and adapted to engage said sockets, pedals carriediby the support, and means for detachably connecting the pedals with the levers.

2. Ihe combination with a piano lyre having a base block provided with upright holes, and levers carried by the lyre and adapted to operate the pneumatic mechanism; of a pedal support including a base adapted to bepassed under said block and having sockets to register with the holes therein, bolts removably mounted in said holes and adapted to engage said sockets, heads at the upper ends of said bolts, pedals pivoted onsaid support, links pivoted to the pedals and adapted to fold under the same when not in use, the free ends of the links having notches, and pins in said levers with which the notches are adapted to engage, for the purpose set forth;

3. The combination with a piano lyre including a head block and a base block, and levers pivoted to the head block with their upper arms adapted to operate the pneumatic mechanism and their lower arms hanging alongside the lyre to points above said base block and there provided with pins; of a pedal support including a base adapted to be passed under said base block, means for connecting said base and block when in operative co-relation, pedals pivotally mounted on said support, and links pivoted to said pedals and having notches adapted to engage the pins on the lower arms of said levers, said links being adapted to be turned under the pedals when the device is not in use.

In testimony whereof we aflix our signatures in presence of two Witnesses.
